Gear casings, R, such as are described in my patent No. 442,459, datedDecember 9, 1890, and Design Patent No. 20,481, dated January 13,1891,are also provided for incasing the pinion r and gear wheel R which arerespectively carried by the armature shaft and the car axle.

I claim as my invention 1. In an electric motor, the combination of asupporting frame, a field-magnet formed in two sections, one sectionhinged to one end of the frame and the other section hinged to the otherend of the frame.

2. In an electric motor, a supporting frame for carrying the armatureand field-magnet, said field-magnet being constructed in two sections,one section being hinged to the said frame upon its upper side at oneend, and the other section being hinged to the said frame upon its lowerside and at the other end.

3. In a motor for street cars, the combination of a field-magnet formedin two sections, a frame, to the opposite ends of which said sectionsare respectively pivoted and bearings formed in said frame for receivingthe axle of the car.

4C. In a motor for street cars, the combination of a cylindrical fieldmagnet having inwardly projecting poles, said field magnet being formedin two sections, a frame to which said sections are independently hingedand bolts normally holding said sections together.

5. In a motor for street-cars, a cylindricalfield-magnethavinginwardlyprojectingpoles, removable separately-woundcoils carried by the respective poles, said field-magnet being formed insections, a frame to which the sections are pivoted upon opposite sidesand at opposite ends, substantially as described.

6. In a motor for street cars, a frame consisting of side bars and thecross bars at the front and rear ends, one of said cross bars havinghinging lugs mounted upon its upper side and the other having hinginglugs mounted upon its lower side.

7. A frame for electric motors consisting of a single casting havingupwardly extending hinging lugs at one end and downwardly extendinghinging lugs at the other end.

S. In a frame for electric motors for street cars bearings for the caraxle at one end, and hinging lugs upon the under side of the frame atthe other end.

In testimony whereof I have hereunto subscribed my name this 6th day ofNovember, A. D. 1891.

ALBERT SOIIMID.
